  • Answer:

    x          y

    -10      -1

    0         4

    4          6

    6          8

    Step-by-step explanation:

    an output is 4 more than half its input.

    Input of a function is x and the output of a function is y

    output y is 4 + half of input x

    [tex]y= \frac{1}{2} x + 4[/tex]

    Now we complete the below table, plug in the value of x  and find out y

    x = -10 , [tex]y= \frac{1}{2}(-10) + 4=-5+4 = -1[/tex]

    x = 0 , [tex]y= \frac{1}{2}(0) + 4=0+4 = 4[/tex]

    x = 4 , [tex]y= \frac{1}{2}(4) + 4=2+4 = 6[/tex]

    x = 8, [tex]y= \frac{1}{2}(8) + 4=4+4 = 8[/tex]
